ferred to herein as a drum container, the inhit vention is concernedwith a container essentially round in cross section, while it may becylindrical or conical. The invention is concerned particularly with theend head construction of such a container and the manner in which it isassociated with the body of the drum container. Among the objects of theinvention is the provision of an end head construction for drumcontainers, which is so constructed that it can be secured to the drumas by means of stitches or rivets, or thread or wire sewing, and yetprovide a substantially leak-proof container. At the same time, theconstruction is such as to form a material reinforcement for the endedges of the drum, which is particularly advantageous with largecontainers, which vary probabl in their handling, will be rolled ontheir end edges, also stacked on end, and conveyed in upright positionon conveying trucks.

In the accompanying drawing:

Fig. 7 is a sectional view taken through an end head ring at itsoverlapping ends when said end ring is made from a suitably shapedlength of material.

Fig. 8 is a perspective view of the end of a container as shown in Fig.1.

The body of the container, as illustrated in 1929. Serial No. 366,795.

Fig. 1, is cylindrical and it is composed of a wall 1. The body of thecontainer may be made up in a number of different ways; for

example, a single piece of fiber board material may be shaped intocylindrical form with its opposite marginal portions overlapping. Themarginal portions may be secured together as by means of the rivets, orwire stitches 2. This forms a vertical seam in the cylinder. Thevertical seam may be constructed, as illustrated in Fig. 3, wherein themarginal edges of the cylindrical wall are brought into substantialabutting relation, and a securing strip is provided, which bridges theabutting edges and which is stitched, or riveted to each by means ofdevices 4. The bridging strip 3 may be placed either inside or outsideof the container. and as shown in Fig. 3, it is in the inside. There areat present available, winding machines which provide cylindricalcontainers by helically wound fibrous material, and the drum or cylindermay be made up in this manner it desirable.

One or both ends of this cylindrical container may be closed by the headnow to be described. This end head comprises essentially what may betermed an end head ring 10. This ring is of channel formation, or U-shaped in cross section. The U is inverted in the case of the top end ofthe cylinder. The marginal edges of the cylinder are fitted into the Uformation so that one leg of the U, as illustrated at 11, fits aroundthe outside marginal edge of the cylinder, while the other leg 12 fitswithin the marginal edge of the cylinder. The bight portion 14 isdesigned to be urged down in contact with the edges of the containerwall in a manner later to be described, so as to form a very tightclosure. This end head ring is provided with an inwardly extendingflange portion 15, for the purpose of supporting the body of the endhead. As shown in Fig. 1, the end head proper is composed of two discsof suitable iiber board or the like 16 and 17. The disk 17 is of a size,preferably. as to snugly fit into the cylindrical container. while thedisc 16 is slightly smaller so as to fit within the portions 12 of theend head ring.

With this construction, the discs 16 and 17 may be secured, andpreferably are secured, to the flange 15, as by means of suitable wirestitches or rivets 18, while the end head is held in place to the bodyof the container, as by means of suitable wire stitches or rivets 19,which extend through the legs of the U and marginal portion of thecylinder. It is, of course, feasible to secure the said parts togetherby means of sewing with thread or wire, or in some instances, where itis desirable, glue could be used.

The end head ring can be constructed in different ways. For example, itmay be stamped out of a sheet of suitable material, and formed intoshape by dies or the like, but it is preferable to form it from a stripof suitable fiber board material or metal. lln this event, anappropriate length of material is required, and preferably, it is firstshaped into the proper cross sectional shape and then bent or spun intocircular shape, with its ends overlapping, as illustrated in Fig. 7. Theoverlapping ends may be secured together as by means of one or morestitches or rivets 20. A problem is presented herein, of thedifferential between the inner and outer diameters of the flange 15 whenthe end head ring is made from a strip of material as just described. Itis thought to be preferable to form the end head ring by distorting thematerial in the flange 15; by this is meant that the material may becompressed somewhat near its inner diameter. This may be expedited bysoftening the flange by means of steam or water treatment. The end headring can be provided, however, by cutting the same radially, as at 21(Fig. 6) to permit of slight overlapping of the material adjacent theslots when the same is formed into ring shape. Satisfactory results havebeen obtained by making the end head ring without the radial slots, andthis is preferred.

Varying requirements of a container of this nature are such thatdifferent types of heads may be employed in containers. designed fordifferent usages. For example, in Fig. 4 the end head of the containeris shown as consisting of merely one disc 1666, which is placed on theoutside of the flange 15 of the end head ring. In Fig. 5 the end headconsists of a single disc 17a, which is placed on the inside of theflange.

There are a number of advantages to this head formation. One is that asift-proof end head is provided for a container of the type described.This is accomplished by reason of the fact that disc 17 relativelytightly fits into the drum and also due to the fact that in securing theend head to the drum the same is urged against the drum until the edgesthereof tightly abut against the bight portion 14 of the U formation ofthe end head ring. Thus a double seal is provided. Of course. where theseal need not be so secure, an end neeaees head construction such asshown in Fig. 4: may be used. However, a very satisfactory seal isprovided by the end of the container abutting into the bight portion ofthe U of the ring. The end head construction, as shown in Fig. 5provides for the double seal, yet does not afford the strength of thedouble head as in Fig. 1. Another advantage is that the head isuniformly positioned, so that a multiplicity of containers of thischaracter are exactly uniform. In other words, the end head of eachcontainer is exactly positioned by the end edges thereof abuttingagainst the bight portion of the U. This not only adds to the appearanceof the containers, but facilitates handling and stacking of the same.

Preferably, the material used for making the end head ring, is such thathas a relatively high resistance to wear, or in other words, ofrelatively tough fibrous material especially in containers of largesize. This is done because containers of this nature are usually stackedon end, and when moved from place to place, are often rolled on edge.Also the end head ring can in some instances, be made of metal wherethis is desired.

Claims:

1. A fiber board container comprising, a drum-shaped body, an end headring having a U-shaped formation in cross section and separate from thebody, said end head ring being placed onto the end of the body with thebight portion of the U abutting against the edge of the drum body andwith the legs of the U lapping the inner and outer sides of the wall ofthe drum body, a plurality of metallic stitches circumferentiallyarranged and in spaced relation extending through the legs of the U andmarginal portions of the drum wall for securing the end head ring to thedrum body, an inwardly projecting flange carried by the end head ring,and a fiber disc-like end head closure member overlapping said flangeand metallic stitches securing the same thereto.
